Question:
Hey! Thanks in advance. I asked this question for another tube, but this looks like a good choice...so My Digitech RPM-1 manual says to only replace its lone tube with a 12AX7A. It is a stereo device, if that makes any difference. Anyway, what is the difference between a a 12AX7, a 12AX7A and a 12AX7WA?! I would like a warm, immediate fuzzy tone to my rotary emulation, but shopping is hard being limited to just 12AX7A's... Know the difference? Any recommendations knowing i prefer warm and fuzzy vs the current sharp and thin tone I am getting? Again, thank you in advance....
